What you'll need:
A Chi-qoo Kit -- The kits are available for purchase from the BootstrapSolar website, but since it's Open Source, you could theoretically make your own from scratch too!
#1 Philips Screw Driver -- That's the "+" type, and a pretty small one.
Glue -- Any glue that works with wood. Standard wood glue will work, though "5 minute" epoxy probably offers the best balance between bonding strength, time to undo mistakes, and curing time.
Time -- Most folks have reported finishing the kit in an hour or less (and as little as 10-15 minutes for those who are handy).
Step 1: Check Your Components
6x wall sections (thin bamboo sections)
1x USB port bezel (says "USB 2" and "i-devices")
1x DC port bezel (says "A" and "B")
1x bamboo bottom plate
1x plastic top plate
1x 6000mAh Lithium Polymer battery
1x USB charger circuit
1x Solar charger circuit
1x Double-ended cable
4x roll pins
16x 3/8" #2 screws
Step 2: Assemble the Wall Sections
1. First note that the wall sections are not left-right symmetrical (as laid out in the first photo).
2. Pick one piece (any piece) and insert roll pins into the larger holes. If the fit is tight, gently tap the pins. Be careful not to stab yourself with the pins though.
3. Once both pins have been inserted fully, apply a small amount of glue. Avoid gluing around the roll pins.
4. Stack the next wall section on top of the first one, again, making sure the roll pins go through the larger holes
5. Repeat for the 3rd piece.
6. Repeat steps 1 through 5 using the other 3 pieces so that you have two wall sections.
7. Wait for the glue to cure before proceeding.
8. Use the 220 grit sand paper (included in the kit) to remove some of the excess carbon residue.
9. In some of the kits, the pins may be longer than the walls are tall. If this is the case, simply use one of the screws to poke them out.
Step 3: Screw on Top & Bottom Plates
Step 4: USB Port Bezel
1. Stand up the enclosure exactly as shown in the photo. The side with 3 holes in the bottom plate should be up (or the engravings on the bottom plate should read bottom up).
2. Without gluing try fitting in the bezel.
3. If it doesn't fit, use the sand paper to sand down the edges until it does fit.
4. Apply a drop of glue to the middle of the wall sections. DO NOT put glue on the corners, or you might inadvertently glue on the top/bottom plates!
5. Place in the bezel. Make sure the text shows so that the plastic top cover is "up" and the bamboo bottom plate is "bottom".
Step 5: DC Port Bezel
Important: If your bezel says "L" and "R", you have a Beta kit. See the instructions here.
1. Make sure the enclosure is oriented as shown in the picture, with the 4 holes in the bottom plate up.
2. Without glue, try fitting the bezel.
3. If it doesn't fit, sand down the edges until it does fit
4. Apply a drop of glue to the middle of the wall sections. Again, don't put glue on the corners to avoid gluing on the top and bottom plates!
5. Place the bezel with "A" and "B" facing out, and closer to the bamboo bottom plate.
Step 7: USB Charger Circuit
1. Place the USB charger circuit so that the USB ports stick out through the USB port bezel, and the holes in the circuit board align with the screws from the previous step.
2. Grasp the enclosure and USB charger circuit as shown in the photo (I'm a lefty, so reverse as necessary).
3. Flip over the enclosure while keeping the USB charger circuit in place.
4. Tighten the 3 screws (make sure the screws are engaging the holes in the circuit board)
Step 8: Solar Charger Circuit
1. Place the solar charger circuit so that the black barrel jacks stick out the DC port bezel, and the 4 holes on the circuit board align with the screws. (Important note below)
2. Grasp the enclosure and circuit board as shown in the picture
3. Tighten the 4 screws (make sure the screws are engaging the holes in the circuit board).
Update: Some kits have shipped with bezels that were not cut to the correct dimensions. As a result, the barrel jacks may not go through the port openings very easily. One solution is to file away a bit of material off the top of the barrel jack, or to use the sand paper or a knife to make the port opening a bit taller. In either case, only about 0.5mm (1/32") needs to be removed.
Step 9: Connect Solar Charger Circuit to USB Charger Circuit
On the solar charger circuit, make sure the cable plugs into the socket labelled "LOAD" (the socket closer to the wall sections).
Note: The cable connector has a protruding ridge and the socket has a matching slot. Make sure they line up!
Step 10: Install Battery
Important note about Lithium Polymer batteries:
While safer than standard Lithium Ion batteries, Lithium Polymer batteries may be damaged and even combust if misused. To avoid damage and/or injury, observe the following precautions:
1. Only charge the battery using a Li-Ion/Li-Poly charger (such as the one included in the kit)
2. Never pierce or puncture the battery pack's aluminium casing
3. Do not short circuit the battery
4. Do not overheat the battery
5. If you notice any swelling in the battery pack, immediately disconnect if safe to do so, or otherwise move to a location where there are no flammable materials.
Step 11: Attach Top Cover
Step 12: Odd Bits and Stuff
Don't worry, you didn't miss anything. We include one extra screw as a spare.
What's this black block?
That's a jumper, and it's used to upgrade one of the USB ports at your discretion.
How do I get rid of these smudges?
The bottom plate (and all the other enclosure parts) are laser cut and etched (we do it ourselves at TechShop!), and the laser etching process sometimes leaves this tacky residue on the surface. You can remove it with diluted vinegar.
Step 13: Charge Your Device!
Which port should I use?
Most Apple devices (iPods, iPhones, iPads) will only work from the USB port labeled "i-devices". Other devices, however, may also work from that port.
Upgrading the "USB 2" port
Some devices will charge (or charge faster) if you upgrade the "USB 2" port to what is called a Dedicated Charging Port. For example, some devices like the Palm Pre and Verizon MiFi will not charge at all from the stock USB 2 port, but will charge if upgraded to a DCP. Read this article for more info.
Step 14: Test Solar Charging!
Some things to know:
* Solar panels work best in direct sunlight with absolutely no shadows
* Solar panels generate the most power when pointed directly at the sun, as opposed to at an angle
* DO NOT leave the battery pack exposed to direct sunlight. Place it behind the solar panel as shown in the photo.
* Solar panels may work through windows, especially old windows. However, modern "Low-E" glass (also used in cars) block a lot of energy.
* What do the LED indicators mean?
* Notes on using two solar panels
